Abstract: Effects of elastic field interactions between precipitate droplets are incorporated in the statistical theory of Ostwald ripening developed by Tokuyama and the present authors. We find that the elastic effects begin to play important roles in coarsening behavior when the average droplet radius reaches the size α/|B|φ where α is the capillary length, φ is the droplet volume fraction and B is the dimensionless strength of the elastic misfit between the precipitate and the matrix. We see that when the elastic field interactions are attractive, coarsening slows down and simultaneously the droplet size distribution tends to become narrow and symmetrical. When the elastic interactions are repulsive the coarsening is accelerated and the droplet size distribution broadens with positive skewness.
